Prime Minister Christopher Luxon spoke with his British counterpart Sir Keir Starmer on Wednesday night to discuss the Iran and Ukraine wars, as well as the cost of living.
Luxon said he spoke with Starmer about high fuel prices, and the pain they were causing Kiwi households.
"We agreed on the importance of diplomacy to reopen the Strait of Hormuz and get shipping flowing freely again," he said.
"Both the UK and New Zealand are steadfast in our support for Ukraine, so it was good to compare notes on how to maintain the pressure on Russia."
The UK was an important partner to New Zealand, Luxon said, adding that the countries were "doing a lot together" to advance prosperity and build global security.
A statement from Downing Street said Starmer began the phone call by thanking Luxon for New Zealand's support for the Coalition of the Willing on Ukraine, and plans for a future multinational mission to reopen the Strait of Hormuz.
Luxon has had a number of discussions with world leaders about a potential mission.
"Ahead of New Zealand's Budget tomorrow, the leaders discussed the financial impact that widespread global instability was having on households in both the UK and New Zealand, and the importance of finding a way forward and ultimately, a resolution, to keep the cost of living down," Starmer's office said.
"On Ukraine, the Prime Minister thanked Prime Minister Luxon for New Zealand's strong support for both the training of Ukrainian soldiers as part of Operation Interflex, as well as Ukraine's efforts to secure a just and lasting peace."
The statement said the leaders also reiterated their call for the Israeli government to "end its expansion of settlements and administrative powers and ensure accountability for settler violence".
